ARZENO J. DILLEY, 0F IONIA, MICHIGAN, ASSIGNOR TO STANLEY VEHICLE SPRING COMPANY, INC., OF SYRACUSE, NEW YORK, A CORPORATION OF NEW YORK.

SELF-LUBRICATING VEHICLE-SPRING.

Application filed September 16, 1915, Serial No. 51,039. Renewed July 9, 1917.

To all w/wm 2'25 may concern:

Be it known that I, ARzriNo J. DILLEY, a citizen of the United States, residing at Ionia, in county of Ionia and State of Michigan, have invented certain new and useful Improvements in Self-Lubricating Vehicle- Springs, of which the following is a specification.

My invention relates to an improvement in self-lubricating vehicle springs, and the object is to provide a dustless self-lubricating leaf spring, the members of which will not stick from friction, but will be sufficiently lubricated at all times to permit freedom of action without unduly catching or accumulating dirt and dust.

ith these objects in view, my invention consists of superimposed leaves, having perforated depressions stamped in their outer ends, in connection with a cap approximately fitting the depressions and the holes therein, and inclosing an absorbent disk, which bears upon the leaf below and forms a means of lubricating it.

In the accompanying drawings Figure 1 is a view in longitudinal section;

Fig. 2 is a view of one of the leaves; and

F ig'. 3 is an edge view of one of the caps with the absorbent disk separated therefrom.

The numerals 1, 2 and represent the lower, intermediate and upper leaves of my improved self-lubricating spring, all of which are secured together at the center in any approved manner, as for instance by a bolt 4 or similar means. I i

All but the lowermost leaf preferably have a depression 5 stamped in the outer end thereof, in the center of which is a hole 6.

A cap 7 of corresponding shape is adapted to fit each depression, and a button 8 at the center of the cap substantially fits the hole 6. or other absorbent material 9 is held in contact with the leaf below.

These springs are of few parts, all of Specification of Letters Patent.

Beneath the cap, a pad or disk of felt Patented Sept. 18, 1917.

Serial No. 179,572.

which are easily made and can be assembled with facility, and in actual tests they have demonstrated their ability to keep the members sufliciently lubricated without being too fluid, thereby wasting lubricant and making the parts greasy, dirty and unsightly; but by this means they are kept clean, free from dust and dirt, while wear and noise due to friction is precluded.

It will be seen from the construction'described, that the buttons on the caps approximately fill and fit the holes in the depressions, although ample space isleft for lubricant, the oil being poured in through the perforations or holes in the depressions, and thence finding its way in the space between the caps and the depressions to the absorbent disk, and thence to the leaf below so that a very few drops in each perforation will keep the leaves amply lubricated, and the springs are kept free of surplus oil.

\Vhile I have shown my invention applied to a cantaliver spring, it is perfectly obvious that it is applicable to any leaf-sprinq.

1 claim p 1. A self-lubricating spring" comprising leaves secured together, their ends having recesses and caps which approximately fit the recesses, and an absorbent disk interposed between each cap and the adjacent leaf of the spring.

2. A self-lubricating spring comprising leaves secured together at the center, their ends having perforated depressions in connection with caps which approximately fit the depressions, said caps each having a button which enters the perforation in the depression, and an absorbent disk interposed between the cap and the adjacent leaf of the spring.

In testimony whereof I aflix my signature.
